Several broken lines of storms are expected to develop well north of Columbus this afternoon near a quasi-stationary boundary across southern Michigan. As the evening wears on, some of these storms could push south closer to Columbus. With highs in the 90s again and very high humidity, the air mass overhead will be quite unstable.
Today’s severe threat will be conditional on storms actually making it all the way down to Columbus this evening which is still not entirely certain. However if they do, some storms could contain strong wind gusts in the form of microbursts and extremely heavy rainfall especially after 6 p.m. The highest threat for storms and consequently severe weather will be north of I-70 this evening.
For this afternoon, a pop up storm cannot be ruled out although most of the area is expected to remain dry under the influence of a strong ridge of high pressure aloft in the atmosphere.
With the high pressure ridge weakening further for the remainder of the week, thunderstorm chances will increase each day. Expect scattered activity on Thursday and right through the upcoming weekend. Right now it looks like Friday will pose a higher risk for widespread storms than Thursday. Temperatures will ever so slowly nudge down into the upper and eventually middle 80s.
